ent two contacting points 1 and 5 on one side,

and three contacting points 6, 7 and 8 on the The high points or contacting points 1 and 5 are provided with oppositely struck out members 9 and 10. This entire member, as shown in Fig. 3, is formed of a single piece in a novel manner as will be later described.

The member 1 forms both a right. and left hand member, and the ends of the semi-circular members 2 and 3 are merely formed with V shaped joints which may be termed universal V shaped joints, as the one member 2is provided with a projecting V joint 11, and

the other member 3 is provided witha recessed V joint 12. The member 1, as well as the joints 11 and 12, make it a universal memher as, regardless which member is picked up, it will form either a right or left hand memberv and the joints will always fit. In ordinary construction now on the market the oval ring member inserts are formed with joints of complicated manufacture so as to make them universal, as otherwise, it would be necessary for the person assembling the member to pick out the correct ring insert at each point of assembly.

. .While my'novel hook carrying toggle plate may be utilized in practically any type of shell member, I have shown a shell member and means for securing the same to the hack of the binder which is peculiarly adapted and cooperates with my novel paper receiving and supporting member. This shell member may be generally designated 13. It is manufactured by taking a piece of strip stock, preferably the length of the back of the cover, and suitable apertures 14 punched therein and spaced a suitable distance apart according to the punching in the sheets of paper. The flat connecting portions of two members 1, as shown in Fig. 3, may then be inserted in the shell structure with the semi-circular parts 2 and 3 extending through the apertures 14;, as shown in Fig. 2. The edges 15 and 16 of the shell 13 are then bent over, as shown in Figs. 2, 4L and 7', whereby the portions 4 and 5 of each member 1 contact and are held in contacting relation by the oppositely struck out portions S) and 10. It will. be seen that the edges 15 and 16 may be bent over much sharper and much flatter than where the connecting shaft for the ring members is a round wire, thus providing a generalbase member which is relatively thin. The oval members flatter than that necessary to be given where plainwire shafts-or connecting members are used, as the space movement of the flat mem: bers 1 is necessarily much less than when the plain round wiremembers are used. It further will be obvious that as the flat members 1 are moved back and forth they will move over a center line'at which point they are compressed against each other by reason of being heldin the channels formed by the turned over edges 15 and 16. This provides for a snap-over movement on opening and closing of the rings. 7

' The ends of the shell member 13 are turned down, as at 17 to provide for a neat appearance, and the side walls of the ends of the shell member are substantially perpendicular to the back of the shell, as shown at 18 and 19 in Fig. 6. As a securing means, I have provided a suitable retaining member or lug 20, as shown in Fig. 5, which is provided with. a suitable aperture 21 for receiving the rivet. The ends of the lug 20 are preferably turned down, as at 22, and are provided with extending portions 23 which lit in the grooves formed by the turned over edges 15 and 16. It will be obvious that the width of the turned down members 22 is approximately the width of the shell at the points 18 and 19, and that the lugs may thus be inserted at the ends of the shell member and be connected to the ends of the shell member by relative movement between the two so that a portion of the lug 20 extends within the turned over edges 15 and 16.

In the preferred use of this shell structure the base member is assembled, as shown in Fig. 7 ,and two lugs 20 are riveted in place on the back of the cover, with the ends 22 extending upwardly, as shown in Fig. 5. The complete shell structure, as shown in Fig. 7 may be then secured thereto by placing one end of the shell over one of the .lugs 20, moving it relative to thelug until the other lug member comes within the opening at the other end of the shell, and the shell member moved back into central position and both lug members thus partially engage the turned down edges 15' and 16 of the shell, as shown in Fig. 4. These flat lug members 20 thus cooperate with the flattened paper retaining and supporting members 1 to permit of a relatively flat base member 13. It will be obvious that other types of shell structure may beutilized, such as that disclosed in my copending application #204c,736,'filed July ll 1927,.but structure herein is thepreferrecl'form as it cooperates with the paper retaining member to permit of a much flatter or thinner shell structure as a whole.

It will be seen thatthe shell'member shown 7 herein, extends'practically the full length of i the binder anclcompletely. covers up all interiorf movable parts and rivets so as'to present a very neat and attractive appearance. The apertures 14 areonthe side of the shellv member so'that the shell member really presents animperiorate upper surtaceextending practically the full length'of the blnder.

The one-p ecepaper receiving and supporting member 1 ispreferably fabricated by first."

shown in Figs, 3, 4t and 7. The n ext'step is to place the bent upilportions 2 and '3 of the Wirein s siitable dies such as shown in Fig. 5, to give the same a substantially oval siape."
